Sessions at UK Hadoop Users Group about Hadoop and Last.fm with video

Unscheduled

Last.fm is well known as an early adopter of Hadoop as a way of storing billions of scrobbles and computing charts from them. We also increasingly use Hadoop to scale more algorithmic tasks to large datasets, and I'll talk briefly about three of our projects in this area:
* topic analysis with Latent Dirichlet Allocation
* graph-based recommendations
* audio analysis
